For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0029] The board-to-board connector provided in the embodiment of the utility model is used to connect the docking board 3 and the mounting board 6, and both the docking board 3 and the mounting board 6 are circuit boards.

[0030] like Figures 1 to 7 As shown, the board-to-board connector includes a base 1 and a terminal 2 fixed in the base 1. The upper front end of the base 1 is provided with a receiving groove 11 for inserting the docking board 3. The terminal 2 has an elastic contact arm 21 extending into the receiving groove 11 and an outer pin 22 extending from the base 1. The base 1 is provided with a pressure cover 4 above the receiving groove 11. The pressure cover 4 is rotatably connected to the base 1, and downward elastic clamping feet 41 are provided on the left and right sides of the pressure cover 4. After the pressure cover 4 is closed, the elastic clamping feet 41 are clamped with the base 1, and the elastic clamping feet 41 are suitable for matching with the clamping holes 31 on the edge of the docking board 3. The base 1 is made of plastic, and the terminal 2 is made of metal.

[0031] The board-to-board connector in this embodiment has significantly fewer components, a simple structure, low manufacturing cost, and also reduces the user's cost of use; when installed and used, the board-to-board connector is installed on the mounting plate 6, and the external pins 22 are welded to the conductive welding positions on the mounting plate 6 to achieve fixed connection and electrical connection with the mounting plate 6. When the pressure cover 4 is opened, the end of the docking plate 3 is inserted into the accommodating groove 11, and then the pressure cover 4 is flipped downward, and the elastic clamping foot 41 is clamped with the base 1 to lock the pressure cover 4, and the elastic clamping foot 41 is clamped into the clamping hole 31 on the edge of the docking plate 3 to lock the docking plate 3, and the elastic contact arm 21 on the terminal 2 contacts the docking plate 3 to achieve circuit conduction.

[0032] like Figure 4 , Figure 6 As shown, in order to realize the pivot connection of the pressure cover 4 on the base 1, a pivot portion 42 is provided at the rear end of the pressure cover 4, a pivot hole 43 is provided on the pivot portion 42, a pivot shaft 12 is provided on the base 1, and the pivot hole 43 and the pivot shaft 12 cooperate to form a rotatable connection.

[0033] like Figure 4 As shown, a positioning column 13 protruding upward is provided on the bottom wall of the accommodating groove 11. When the docking plate 3 is connected, the positioning hole 32 on the docking plate is sleeved with the positioning column 13 to play a positioning role, thereby preventing the docking plate 3 from detaching from the accommodating groove 11 and enhancing the connection reliability.

[0034] The bottom of the accommodating groove 11 is provided with a clearance groove 10 , and after the pressing cover 4 is closed, the bottom end of the elastic clamping foot 41 extends into the clearance groove 10 , and plays a avoiding role through the clearance groove 10 .

[0035] Combination Figure 1 , Figure 4 and Figure 5 As shown, welding pieces 5 are fixed at the left and right ends of the base 1, and the welding pieces 5 are provided with fixed welding feet 51 extending outward. When the board-to-board connector is installed on the mounting plate 6, the fixed welding feet 51 on the welding piece 5 can be welded to the fixed welding positions on the mounting plate 6 to enhance the mounting firmness of the board-to-board connector.

[0036] In some embodiments, the gland 4 is a one-piece metal piece, so that the structure is firm.

[0037] See also Figure 1 As shown, the elastic foot 41 is a U-shaped structure, and a latching protrusion 44 is provided on the outer side wall of the elastic foot 41, and a latching groove 14 is correspondingly provided on the inner side wall of the accommodating groove 11. When the pressure cover 4 is in the closed state, the latching protrusion 44 and the latching groove 14 are engaged, thereby limiting the pressure cover 4 and keeping the pressure cover 4 closed. A pressing handle 45 is provided on the upper end of the outer side wall of the elastic foot 41. When the pressure cover 4 needs to be opened, the elastic foot 41 can be deformed by pressing the pressing handle 45, so that the latching protrusion 44 is disengaged from the latching groove 14, and then the pressure cover 4 can be flipped upward to open.

[0038] like Figure 1 As shown, overlapping edges 46 are provided on both sides of the pressure cover 4. When the pressure cover 4 is in the closed state, the overlapping edges 46 are suitable for overlapping the upper ends of the side walls of the accommodating groove 11. In this way, the upper ends of the side walls of the accommodating groove 11 can support the pressure cover 4 by abutting against the overlapping edges 46, thereby enhancing the pressure resistance of the pressure cover 4.

[0039] like Figure 3 As shown, in order to increase the reliability of the connection between the terminal 2 and the docking plate 3, the terminal 2 is provided with two elastic contact arms 21, and the two elastic contact arms 21 are relatively independent. When the two elastic contact arms 21 are in contact with the docking plate 3, there are more contact points, and the electrical conduction performance is more guaranteed. Moreover, when one of the elastic contact arms 21 is damaged or cannot be in good contact with the docking plate 3, it will not affect the contact between the other elastic contact arm 21 and the docking plate 3, thereby ensuring the normal conduction of the circuit. The elastic contact arm 21 is provided with an upwardly protruding contact point 23, through which the contact point 23 is in contact with the docking plate 3.

[0040] When the mounting plate 6 uses an aluminum substrate, since the aluminum substrate is conductive, the contact between the external pin 22 and the edge of the aluminum substrate will cause a short circuit. In order to better solve this problem, the structure of the external pin 33 is optimized in this embodiment: the external pin 22 includes a connecting portion 221 in the shape of a "7" with a downwardly bent end and a welding foot portion 222 extending backward from the end of the connecting portion 221. In this way, when the board-to-board connector is installed on the mounting plate 6, the above-mentioned connecting portion 221 can better adapt to the avoidance of the edge of the aluminum substrate, and the bottom edge of the welding foot portion 222 is welded to the conductive welding position on the mounting plate to avoid contact short circuit. For specific structure, please refer to Figure 7 shown.

[0041] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
